Definitions

  • the present invention relates to a radiation source module for use in a fluid treatment sytem. In another of its aspects, the present invention relates to a fluid treatment system incorporating a radiation source module.
  • Fluid treatment systems are generally known in the art. More particularly, ultraviolet (UV) radiation fluid treatment systems are generally known in the art.
  • UV radiation fluid treatment systems are generally known in the art.
  • Such systems include an array of UV lamp modules (e.g., frames) which include several UV lamps each of which are mounted within sleeves which extend between and are supported by a pair of legs which are attached to a cross-piece.
  • the so-supported sleeves (containing the UV lamps) are immersed into a fluid to be treated which is then irradiated as required.
  • the amount of radiation to which the fluid is exposed is determined by the proximity of the fluid to the lamps, the output wattage of the lamps and the flow rate of the fluid past the lamps.
  • one or more UV sensors may be employed to monitor the UV output of the lamps and the fluid level is typically controlled, to some extent, downstream of the treatment device by means of level gates or the like.
  • the Maarschalkerweerd #1 Patents teach fluid treatment systems which were characterized by improved ability to extract the equipment from a wetted or submerged state without the need for full equipment redundancy. These designs compartmentalized the lamp arrays into rows and/or columns and were characterized by having the top of the reactor open to provide free-surface flow of fluid in a "top open" channel.
  • the fluid treatment system taught in the Maarschalkerweerd #1 Patents is characterized by having a free-surface flow of fluid (typically the top fluid surface was not purposely controlled or constrained).
  • a free-surface flow of fluid typically the top fluid surface was not purposely controlled or constrained.
  • the systems would typically follow the behaviour of open channel hydraulics. Since the design of the system inherently comprised a free-surface flow of fluid, there were constraints on the maximum flow each lamp or lamp array could handle before either one or other hydraulically adjoined arrays would be adversely affected by changes in water elevation. At higher flows or significant changes in the flow, the unrestrained or free-surface flow of fluid would be allowed to change the treatment volume and cross-sectional shape of the fluid flow, thereby rendering the reactor relatively ineffective.
  • the improved radiation source module comprises a radiation source assembly (typically comprising a radiation source and a protective (e.g., quartz) sleeve) sealingly cantilevered from a support member.
  • the support member may further comprise appropriate means to secure the radiation source module in the gravity fed fluid treatment system.
  • the Maarschalkerweerd #2 Patents are characterized by having a closed surface confining the fluid being treated in the treatment area of the reactor.
  • This closed treatment system had open ends which, in effect, were disposed in an open channel.
  • the submerged or wetted equipment UV lamps, cleaners and the like
  • pivoted hinges, sliders and various other devices allowing removal of equipment from the semi-enclosed reactor to the free surfaces.
  • the fluid treatment system described in the Maarschalkerweerd #2 Patents was typically characterized by relatively short length lamps which were cantilevered to a substantially vertical support arm (i.e., the lamps were supported at one end only). This allowed for pivoting or other extraction of the lamp from the semi-enclosed reactor. These significantly shorter and more powerful lamps inherently are characterized by being less efficient in converting electrical energy to UV energy. The cost associated with the equipment necessary to physically access and support these lamps was significant.
  • Maarschalkerweerd #3 teaches a closed fluid treatment device comprising a housing for receiving a flow of fluid.
  • the housing comprises a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet, and at least one radiation source module disposed in the fluid treatment zone.
  • the fluid inlet, the fluid outlet and the fluid treatment zone are in a collinear relationship with respect to one another.
  • the at least one radiation source module comprises a radiation source sealably connected to a leg which is sealably mounted to the housing.
  • the radiation source is disposed substantially parallel to the flow of fluid.
  • the radiation source module is removable through an aperture provided in the housing intermediate to fluid inlet and the fluid outlet thereby obviating the need to physically remove the device for service of the radiation source.
  • the device comprises a housing for receiving a flow of fluid.
  • the housing has a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet and at least one radiation source having a longitudinal axis disposed in the fluid treatment zone substantially transverse to a direction of the flow of fluid through the housing.
  • the fluid inlet, the fluid outlet and the fluid treatment zone are arranged substantially collinearly with respect to one another.
  • the fluid inlet has a first opening having: (i) a cross-sectional area less than a cross-sectional area of the fluid treatment zone, and (ii) a largest diameter substantially parallel to the longitudinal axis of the at least one radiation source assembly.
  • arrangement (ii) in a UV radiation water treatment system has been based on the theory that radiation was effective up to a prescribed distance from the radiation source, depending on the transmittance of the water being treated. Thus, it has become commonplace to interspace the radiation sources in arrangement (ii) such that the longitudinal axes of adjacent radiation sources are spaced at a distance equal to approximately twice the prescribed distance mentioned in the previous sentence.
  • United States patent 5,503,800 [Free] teaches an ultraviolet sterilizing system for waste water adopting arrangement (ii) described above.
  • channels are formed around a single lamp assembly and projections are formed in the channels to induce turbulent plug flow such that when the apparatus is inserted into a flow of liquid to be treated, the channels act to confine and direct liquid about the housing and the projections act to establish a continuous, cyclical flow in the channels between housing and the channels walls.
  • This system has disadvantages since it requires individual channels be provided between a wall structure and a single lamp assembly. Thus, when treating large volumes of water, it is necessary to utilize a plurality of radiation source assemblies.
  • the present fluid treatment systems uses a combination of the radiation source assembly and a prescribed wall structure to encourage fluid flow along the sides of the walls of the fluid treatment zone while obviating or mitigating short circuiting (i.e., the phenomon where fluid travel along the wall is not subject to a sufficient dose of radiation).
  • fluid treatment system taught by Ma relies on relatively uniform fluid flow from side to side in the fluid treatment zone while obviating or mitigating short circuiting.
  • a radiation source module for use in a fluid treatment system comprising an open channel, the radiation source module being defined in claim 1.
  • Preferred embodiments of the radiation source module are defined in claims 2-8.
  • a fluid treatment system according to the invention and comprising a pair of radiation source modules according to the invention is further defined in claim 9.
  • the present radiation source module is, on the one hand, moveable in and out of the open channel in which fluid is flowing, while on the other hand, able to act as an independent fluid treatment system in that it contains sidewalls and a floor element which cooperate to contain a flow of fluid in which radiation source assemblies are disposed. While many of the embodiments disclosed below utilize distinct sidewalls and floor portions in the radiation source module to achieve this goal, it will be appreciated by those of skill in the art that the use of sidewalls and floor elements is not particularly required and, for example, a cross-sectional shape of the treatment area of the radiation source module could be somewhat continuous or curvilinear so as not to contain distinct sidewalls and floor elements yet still function in accordance with the teachings of the present invention. Such modifications are of course encompassed by the present invention.
  • module removal devices are illustrated which remove the radiation source module from the fluid treatment system by rotation or linear translation.
  • rotation or linear translation it may be possible to modify these specific embodiments to achieve removal of the radiation source module without relying only on rotation or linear translation. Again, these modifications are encompassed by the present invention.
  • Figures 1-21 illustrate various preferred embodiments of the present fluid treatment system and the present radiation source module.
